NVD · uneditedImproper authentication in Samsung Pass prior to version 4.2.03.1 allows local attacker to access stored account information when Samsung Wallet is not installed.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSamsung Pass prior to version 4.2.03.1 contains an improper authentication vulnerability that allows a local attacker to bypass security checks and access stored account credentials. The authentication mechanism is weakened when Samsung Wallet is not installed on the device, enabling unauthorized access to sensitive credential data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Samsung Pass app versionOpen Settings > Apps > Samsung Pass, or run `adb shell dumpsys package com.samsung.android.spass` and locate the versionName fieldAffected if Version is lower than 4.2.03.1
-
Verify if Samsung Wallet is installedCheck Settings > Apps > Samsung Wallet, or run `adb shell pm list packages | grep samsung.android.wallet`Affected if Samsung Wallet is NOT installed on the device
-
Confirm authentication bypass conditionIf Samsung Pass version < 4.2.03.1 AND Samsung Wallet is absent, the weakened authentication mechanism described in the CVE is presentAffected if Both conditions are true: Samsung Pass version < 4.2.03.1 AND Samsung Wallet is not installed
A device is affected if it runs Samsung Pass version below 4.2.03.1 and does not have Samsung Wallet installed, allowing bypass of the authentication mechanism to access stored credentials.
